baby 10 sequencer

The bi-directional sequencer utilizes a 4-bit binary up/down counter (CD4516) and two "1 of 8 line decoders" (74HC138 or 74HCT138) to create the well-known "Night Rider" display. A Schmitt Trigger oscillator generates the clock signal for the counter, with...

The output of the 4017 has a 100% duty cycle, meaning that if step one and step two are activated, they will overlap, resulting in a step that lasts for two cycles. In contrast, the output of the 555...

This project has been contemplated since the first attendance at a concert by Institut für Feinmotorik, a German band known for their unconventional use of turntables to produce sound and noise. What was most striking about their performance, aside...

Various types of paper were tested, including photo paper, telephone book paper, color magazine pages, dextrin-coated paper, and catalogs from electronic supply companies. Different temperatures of a hot iron and varying pressure levels were also experimented with. Several board...

This project is classified as intermediate to advanced, and it is not recommended for beginners in synthesizers or electronics. The circuit and some explanations are provided, assuming prior experience in project building, troubleshooting, and electronics. Ownership of electronic equipment...

The baby-alert transmitter is constructed using an LM324 quad operational amplifier (U1), two LMC555CM CMOS oscillator/timers (U2 and U3), along with several supporting components. The transmitter activates upon detecting sound at MIC1, emitting a signal. Its operational frequency is...
